Jul 1, 2013 at 10:19 comment added Tobias Kienzler Well obviously the right hand side needs to be fixed into $i\cdot (n+1)$...
Jun 30, 2013 at 17:35 comment added Hagen von Eitzen @GEdgar I think $sin$ vs. $\sin$ is rather a typographic or $\LaTeX$ usage mistake, not a math mistake.
Jun 26, 2013 at 23:57 comment added Jeff Damn, foiled again. Or should that be metafoiled?
Jun 26, 2013 at 23:54 comment added Casey Chu @Jeff The index $j$ should be $i$.
Jun 26, 2013 at 18:30 comment added Jeff I see nothing wrong with the displayed equation, so I presume that someone took the liberty of correcting it without saying anything.
Jun 24, 2013 at 16:37 comment added Doug Spoonwood @GEdgar I think it's a sin to talk about sin when talking about mathematical sins. (just a pun)
Jun 24, 2013 at 13:49 comment added GEdgar For example, he writes $sin$ instead of $\sin$ but does it correctly elsewhere. Go ahead and put the backslash in.
